The Y62 2017-2021 Nissan Armada and Z62 2011-2023 Infiniti QX56 / QX80 equipped with the 7 speed transmission are geared at 2.93 ratio from the factory. The front and rear differentials from a tow package 1st gen Armada (2003-2015) are geared at 3.36 ratio. If you're lifting your Y62 and running larger tires or doing a lot of towing / hauling and notice your transmission gear-hunting, changing ratios to 3.36 is an excellent upgrade. With this adapter the front and rear diffs from a 1st gen Armada are a direct bolt-in and result in replacing the weaker R180A front differential with the stronger M205 front differential. They're commonly available in junk yards and pick-and-pulls.
